Referring to the drawings, Figure 1, there is shown a fragmentary elevation of a liquid meter housing I having an inlet 2 and an outlet 3 to which is suitably connected a valve casing indicated generally by the numeral 3. The meter may be of any suitable construction or type, the preferred construction being shown and described in the application of Walter H. Parker and Nelson J. Seibert, filed April 9, 1934, Serial No. 719,788. An adapter plate 5 is secured over the distributing chamber of the meter, and a register indicated generally by the numeral 6 is secured to the adapter plate by bolts or in any other suitable manner.

The valve casing 4 is divided by a partition 1 having a valve orifice a therethrough which is normally closed by a compound valve closure member 9, and shown in Figure 1 as held in open position by a trigger latch mechanism adapted to be released, as will presently he described, when a predetermined quantity of fluid has passed through the meter. The valve closure member 9 has guide ribs Iii extending axially thereof which are adapted to engage the wall of orifice 8 to guide the valve in its axial movement. The valve has an integral hollow cylindrical extension ll which is threaded adjacent its base, and a soft washer l2 made of rubber or other suitable material surrounding the extension H is held in position by a backing washer l3 and a nut 14 threaded on the cylindrical extension.

The guide ribs Ill merge at the center and form a space I5 between the ribs which provides a fluid passageway through the valve closure 9, this passageway being adapted to be closed by a smaller valve member It of suitable construction enclosed within the cylindrical extension I I, suitable openings being provided in the wall of the extension H to allow passage of fluid therethrough. A hole I! is formed through the center of the ribs through which passes a short guide stem [8 attached to the valve I6. The valve It has a suitable soft seat I9 adapted to seat against the valve seat 26, and a flange 2| thereon is engaged by a spring 22 which urges the smaller valve i6 and larger valve 9 into closed position.

A threaded opening 23 in the valve casing is provided to enable removal and inspection of the valve and this opening is closed by a removable cap 24 threaded therein. The valve operating stem 26 has a head 21 adapted to engage the end of short guide stem l8. The stem 26 passes through a stuffing box 28 of any suitable construction and is received in a plunger 26" which is adapted to be pushed downward manually by the lug on the operating handle 29 which is of any suitable construction and-is held in upward position disengaged from plunger 26" by a leaf spring 30.

The valves 9 and it are adapted to be held in open position by .a latch mechanism which now will be described. The valve casing t has a latch chamber covered by a plate 25 (Figure 3) and. the operating plunger 26 has a cross head and pin 3| formed thereon which is engaged by the bifurcated ends 32 of the forked bell crank lever 33 rotatably mounted on pin 34 in the latch chamher. The opposite end 39 of the bell crank lever 33 is slotted to receive a roller 35 rotatably mounted on a suitable pin 35 passed through the lever. A second or multiplying bell crank lever 36 is similarly pivotally mounted on a pin. 31 parallel to pin 34 and has a track with a portion 4| curved concentrically about pin 35' and a straight portion 38 on arm 42 thereof. The arm 43 of bell crank lever 36 has a rounded end 44. A third bell crank lever 46 is pivotally mounted on pivots 47 and has arms 48 and 50, with a recess 49 in the hub thereof providing a straight track portion indicated at 5! The latch lever 53 is pivoted on a, pin 54 at substantially a right ".1

angle to the axes of the other levers, and its horizontal arm 55 is adapted to be depressed sufficiently to permit the rounded end of arm 50 of lever 46 to pass thereover and to be latched thereby against return movement. The latch lever 53 has an extension 51 of its arm 58 which is adapted to be moved in tripping direction by a pivoted trip' 58 pinned to shaft 69. A wire spring 58 wrapped around rocker shaft 68 and trip 58 constrains extension 5'! to the right as. seen in Figure 3. Both trip 58 and spring 59 are suitably secured to rocker shaft 66. Rocker shaft 60 is suitably journalled in the Valve casing d and in a flanged bushing 6| suitably secured to the valve casing. The valves 9 and Hi are shown in open position in Figure 1, and in Figures 2 and 3 the latch mechanism is shown in full'lines on an enlarged scale in corresponding position, and in dot and dash lines corresponding to the closed position of the valve.

The trigger latch is adapted to be depressed automatically by the register 6 upon passage of a predetermined quantity of fluid through the meter, as will presently bedescribed. However, an emergency trip is provided sothat the valve may be closed manually at any time. This trip comprises a plunger suitably journalled in the valve casing and held outward by a spring 66- so that normally its inner end is not in engagement with extension 56 of lever 53-.

A sleeve 61 is pinned to the inner end of plunger 65 to hold the plunger and spring 66 in assembled relation. By manually pushing plunger 65 inwardly it engages extension 56 and trips latch arm 55 thus releasing arm 50 to allow the spring 22 to simultaneously close valves 9 and IS.

The register comprises a casing 10 in which is. secured a framework ll carrying the register mechanism, the register case l6 being closed at its bottom by a plate 12. A meter driven shaft 13 passes through a central bushing M therein, said shaft being adapted to be driven from the meter I by suitable gearing (not shown). The shaft 13 is connected to vertical shaft 15 by an Oldham coupling 76 or any other suitable connection. Theshaft i5 is journalled in the frame H and carries a bevel gear 11 for driving bevel gear 78 on totalizing counter drive shaft 79 which drives the totalizing counter 80, and a worm Bl cooperating with worm wheel 82 drives unit indicator shaft 83 through asuitable friction coupling.

The reduction shaft 84 which is offset from shaft 79' is frictionally coupled to a gear 85 thereon which is driven from gear 86 on shaft 83. Pinion 81 on shaft 84 drives the integral spur gear and sleeve 88 rotatably secured on shaft 83,and the indicators or dials 9E! and-83 are driven by shaft 83 and gear 88 respec'tivelyto indicate units and sub-total gallons. The drive for the indicators 89 and 90 is more fully described in the copending application of Nelson J. Seibert and Walter H. Parker filed November 3,1932, Serial No. 641,098.

A second worm 9| onshaft 15. cooperates with a worm wheel 92 onthepredetermining counter driving shaft 93 which is suitably journalled in frame H, and has a bevel gear 9t secured at its inner end. A plate 96 (Figures 5 and 6) is secured to the frame H by suitable screws. (not shown) and a plate 555 is secured thereto in spaced relation by acombined spacer and bearing block 9'5 and top spacers lilil to support the predetermin-ing counter mechanism. An intermediate cross shaft 98 is journalled in suitable bushings in said plates and carries a bevel gear 99 adapted. to engage and be driven: by bevel gear 94, and a spur gear lill hereon meshes with the spur gear I62 of the predetermining counter wheel assembly.

The predetermining counter wheel assembly comprises a units counter wheel i6 3, a tens counter wheel I84 and-a hundreds counter wheel H15, all being rotatably'journalled on the counter setting shaft I01, although any desired number of counter wheels may be used. The counter wheels W3, 1 M and F65 are basically similar, so that only wheel Hi3 will be described in detail, and the differences of the other wheels thereover will be pointed out. Wheel [63 com-- prises a numeral cylinder [96 (Figures '6 and 8) preferably made of Celluloid or other suitable material having secured thereon a metal flange I01 with an arcuate notch H6 in its periphery. The corresponding flanges Hi8 and 39 (Figure '6) of counter wheels EM and H35 preferably are of progressively increased diameter respectively, and the bottoms of notches Hi and H2 thereof are'th'e'same distance from the center as the bottom of notch HE. A metal hub H3 (Fig. 8)- extends th-roughthe cylinder H16 on which is centered the flange l-Dl, a notched transfer pinion locking plate H4 (Figures 11 and 12-) and a toothed transfer plate H5, the latter having a registering'notch H5 in its periphery between two teeth. This construction shown in Figure 12 is common to all of the counter wheels.

The unit counter assembly I03 includes the gear spur I02 (Figures 6 and 7) having a notched plate II 1 secured thereto (Figure 7), and a plurality of pawls H8 pivoted on the pins H9 are urged outwardly by the bent leaf springs I20. An internal ratchet wheel I2I (Figure 8) which preferably has forty teeth is secured to cylinder I06, and in assembled position the pawls H8 are urged into engagement with ratchet wheel I2I so that cylinder I06 and plates H4 and H5 thereon are positively driven by gear I02 in one direction. In rotation a tooth of transfer plate I I5 engages a mutilated tooth of mutilated transfer pinion I22 which is rotatably journalled on shaft I23 until the notch H6 in transfer plate H5 and locking plate II4 engages a complete tooth of transfer pinion I22. Pinion I22 engages gear I24 of adjacent counter wheel I04 and when pinion I22 is rotated one-quarter of a revolution the counter wheel I04 is rotated one tenth of a revolution. The notch H6 becomes disengaged from pinion I22 leaving two complete teeth engaging the periphery of locking disk H4 to prevent rotation of pinion I22 and gear I24 while the notch H0 is out of engagement with pinion I22.

Gear I24 (Figure 9) of counter wheel I04 carries two pivoted pawls I25 which are urged outwardly by spring I26, and the numeral cylinder of counter wheel I04 (Figure 10) has a notched insert I21 secured thereto about hub H3. When gear I24 is turned by transfer pinion I22 the pawls I25 engage the notches in insert I21 and rotate the counter wheel I04. In a similar manner, the transfer plate H5 on wheel I04 periodically engages mutilated transfer pinion I28 to rotate gear I24 of counter wheel I05. From the foregoing description it will be seen that the counter wheel I04 makes one revolution for ten revolutions of counter wheel I03, and counter wheel I05 makes one revolution for one hundred revolutions of counter wheel I03.

A weight I30 is pivoted on shaft I3I which is journalled in plates 95 and 93, and carries two downwardly extended lugs I32 in which is journalled a shaft I33 carrying three rollers I34, I35 and I36 (Figures 5 and 13). When the register Wheels I03, I04 and I05 are all set off of zero, roller I35 rides on the edge of flange I09 and holds the weight I30 in elevated position. When the counter wheels all register zero the rollers I34, I35 and I36 fit into the recesses H0, III

and H2 respectively, thus permitting the weight I30 to assume its descended position. The weight I30 is connected by arod I31 to the outer end of link I38 secured on shaft I40, and shaft I40 is coupled to rocker shaft 60 (Figure 1) by a coupling rod MI. The lowermost position of weight I30 is adjusted by screw I42 which engages the top of bearing block 96.

The locking plates H4 on the counter wheels are recessed at I45 (Figure 12) and receive a pivoted pawl I46 which extends into the hole I41 in the hub H3, and is urged inwardly into this position by a hair pin spring I40 in the recess I45. The counter setting shaft I01 has an arcuate notch or recess I49 intermediate its ends, so that when the notch is properly positioned the pawl I46 falls into this notch. An indicator frame I50 (Figure 5) is secured to the setting shaft I01 for longitudinal movement therewith and is so adjusted that when pointer I5I thereon (Figure 1) is opposite a numeral cylinder the pawl I43 of that particular cylinder has fallen into the notch I49 in shaft I01. An extension I52 is suitably coupled to setting shaft I01 and siidably extends through the casing 10 so that it may be moved longitudinally to properly locate the notch I49 in setting shaft I01. The shaft I0? is utilized to set the counter wheels I03, I04 and I95 to indicate a predetermined quantity to be delivered. If desired, a plurality of notches I49 may be formed in shaft I01 side by side in staggered relation to the pawls I46 so that the amount of longitudinal movement of shaft I01 for setting the counter wheels may be reduced. The indicators 59 and can be reset to zero by means of a side ratchet set back extension I55 (Figure I) which carries a bevel gear I55 (Figure 5) on its inner end in mesh with a bevel gear I51 secured on unit shaft 83.

In Figure 12a there is shown a counter assembly taken in diametrical section through the pivot of a pawl I45 showing a modified form of resetting shaft. In this figure the counterwheels I03, I04 and I5 are mounted on a sliding shaft I58, and the counter-wheels are constructed exactly as previously described in connection with Figures 6 to 12. The shaft I50 is shown in position with the notch I59 opposite the pawl I46 of counter-wheel I05 and engaged thereby for resetting operation. With the shaft in this position a notch I59 is formed in the shaft I58 adjacent the notch I59 and intermediate the notch I59 and pawl I46 of counter-wheel I04, and a third notch I59 is formed in the shaft I50 on the opposite side of pawl I40 of counterwheel I04. The notches I59, I59 and I59" are so arranged in staggered relation to the pawls I46 that only one notch can engage one pawl at any time. The advantage of this construction over that shown in Figure 6 is that the resetting operation may be accomplished With a much smaller longitudinal movement of the shaft I50. Upon movement of the shaft I58 to the right for a distance substantially equal to one-third the width of a counter-wheel, the notch I59 is disengaged from its pawl I45 of counter-wheel I05,

and the notch I59 is engaged with its pawl I46 of counter-wheel I04, while the notch I59" is brought closer to pawl I45 of wheel I03 but is still not in engagement therewith. When the shaft I58 is shifted again to the right for a distance of approximately one-third the width of a counter-wheel, the notch I59" engages the pawl I46 of counter-wheel I03 while the notches I59 and I59 are both disengaged from their respective pawls.

The operation of the apparatus now will be described. Let it be assumed that a quantity of five hundred fifty-five gallons is to be delivered. The setting shaft I01 is moved longitudinally until the pawl I45 of units counter wheel I03 falls into the notch I49 on shaft I01 as indicated by the pointer I5I, (Figure 1), and the shaft I01 is then turned counter clockwise as viewed in Figure 5 by means of extension I52 until counter wheel I03 shows the numeral five. During the setting operation pawls H8 (Figure 8) ride over the teeth of ratchet wheel I2I so that the numeral cylinder I06, and with its flange I01, transfer plate H5, and locking plate H4 are rotated while gear I02 (Figures 5 and 7) remains fixed. The shaft I01 is thenshifted till pointer I5I is opposite counter wheel I04, and this wheel is similarly set in counter clockwise direction to the numeral five, the pawls I25 (Figures 9 and 10) riding over the notches in insert I21 to permit the cylinder I06 and its flange I08, transfer plate I I and locking plate M4 to rotate while gear plate I24remainsfixed. Counter wheel I05, is similarly set to the numeral 5. The indicators 89' and 90 are set tozero by means of ratchetset back knob I55, this motion being all'owed by the 'friction drive between shaft 83 and gear 82,-and the friction drive between shaft 84 and gear '85.

The predetermined counter being set at 555 the flow of liquid can now be started. To start the flow of liquid, the valve hand lever29 (Figure 1) is depressed so that lug engages against the end of stem 26, and the operating stem enlarged head 21 first engages valve guide rod I8 to open small valve I6 and relieve the pressure difference on the two-sides of the'valve, and then engages the hub of ribs III to open the large valve. The operating rod now is in the position shown in full lines in Figure 2. The forked lever 3'3'has'been turned from its dot and dash line position by the engagement of cross pin 3I therewith, thereby causing the roller 35 at its opposite end to "engage the curved portion 4| of the track 'onlever'35 and rotate lever36 clockwise from its dot and dash line position. The rounded end of lever 36 thereupon is brought into engagement with the straight side of recess 59 in lever 46 andturns this lever counter clockwise from its dot and dash line position, the rounded end of arm-50 of the lever riding over, and depressing the horizontal latch arm 55 of lever 53 as indi cated by the dot and dash line position shown in Figure-3. The spring wire 59 on rock shaft 65 then returns lever 53 to the full line position shown in Figures 2 and-'3 so that horizontal arm 55 engages and latches the arm 50 in retracted position as-shown in full lines in Figure 2. When the opening lever 20 is released by the operator it rises by the action of spring (Figure 1)-but is not followed by the valve stem' 26 because the stem is locked in its depressed positionas lever '36 is locked against counter clockwise rotation by engagement of rounded end =44 with the straight portion-49 on lever 46, and lever- 33 is locked against clockwise rotation by engagement of roller against the straight-portion 33 of the track on-lever 3'6. Hence, the lever 33i-holds the valves 9 and I6 in open position against the bias of spring 26, and the valve cannot close -untilthe trigger latch arm 55- is rocked counter clockwise to release arm 46.

The flow begins through themeter as soon as the valve I6 is opened, and the operation of the meter turns shaft'13and coupled shaft 15 which drives the unit pointer 90, through worm 8 I ,vvorm wheel-'82 and shaft 83, the subtotal pointer 89 being secured to and driven by :gear 88 which is driven through gear '81, on shaft =84, on gear 85, onshaft 84 and gear 86 on shaft 83. 'Thetotalizing icounter 80 is driven from shaft 15 by bevel gears TI, I8 and shaft I0. I

The worm 9I on shaft 15 drives wormwheel "92 onthe predetermining counter drive shatt 93, whichdrives the counter '-wheels I-03,=-I04 and 1 05 counter clockwise as reviewed in Figuret' in descending direction through bevel gears 54 and 99 and drive gears IM and I02. Theunitscounter wheel I03 is first rotated by the positive en- 'ga'gementof pawls M8 on gear 152 with'the int'erna'l ratchet-wheel I-2 I on numeral cylinder llflfith'ereof. Each time counter wheel-103 makes za co'mplete revolution, which corresponds to ten gallons, the notch I'IG-in transfer disk -I I5- and locking Iidisk H4 receives a complete toothof itransferlp'inion I22 and turns iitlthe interval between two mutilated teethQand the-teeth on pinion I22 engage gear disk I24 of counter wheel I04 to turn it one tenth of a revolution. The edge of locking disk I14 engages two complete teeth to lock the pinion I22 against accidental displacement as the counter wheel I03 continues to revolve. When wheel I04 makes a complete revolution the notch in its transfer disk II5 receivesa complete toothor transfer pinion I28 the teeth of which in turn engage gear disk I24 of counter wheel I05 and turn the latter one tenth of a revolution. The roller I35 (Figure 13) rides on flange I09 which has the greatest diameter and keeps the weight I30 in elevated position. When counter wheel I05 indicates zero the roller I35 falls into notch II2 leaving roller I35 riding on flange I03 until counter wheel I04 indicates zero, etc. Thus, a smaller force is required to drive' the register than if all the rollers at all times engaged 'all the flanges. When all the-counter wheels register zero, all the recesses H2, III and H0 respectively are in alignment and the rollers I36, I35 and I54 drop into the respective recesses thereby permitting weight I30 to drop, until stop screw i42 engages the top of bearing block 96. Through connecting rod I31 the dropping of the weight I30 rocks crank arm I33 secured to rock shaft I40, and by means of the coupling shaft I4I the trip arm 58 secured to rock shaft 50 is rocked clockwise as seen in Figure 3, thus rocking crank lever 53 counter clockwise to depress latch arm 55. The tripping of arm 55 releases arm 50, and the force of spring 22 now simultaneously closes valves I6 and 9 thus shutting ofi the flow when 555 gallons has been delivered. The upward movement of rod 26 places the levers 33, 36 and '46 in the dot and dashline positions shown in Figure 2. Should it be necessary to close the valves I6 and 9, before the full 555 gallons has been delivered the emergency plunger 64 is depressed and its inner end engages extension 51 and rocks lever 53 in tripping direction to release arm 50. When it is desired to reset the predetermining counter wheels, the wheels Hi3, I54 and I05 are individually set as previously described. This causes rollers I34, I35 and 155 to move out of their respective notches and raises weight I30 which, through connecting rod I37, rotates shaft to return trip 50 to its full :line position in Figure 3, the wire spring 59 returning latch lever 53 to its full line position ready for a resetting of the valve.

in the modification shown'in Figures 13 to 20, the register housing IE0 is exactly like the register housing'lii except as hereinafter described, and contains the predetermining counter mechanism. The bottom of the casing I65 seats on a casing WI in which the trigger latch mechanism'is housed, and which in turn-is secured to the fluid meter in any suitable manner. The casing I50 can be rotated on case IBI to any desired position, clamping members IGI or other suitable means being provided for this purpose. The casing IESI comprises a bottom cup shaped recess I52, and -a=cover plate I53 "therefor which is held in position by :four screws I54 passing "through the 'bo'ttomcasing I 5 I :and threaded into the plate I63. The cover plate N53 has four guide posts I55 riveted thereto which have heads 456 at. the upper ends thereof, :and a thin disk or floating member I51 'has :holes therein loosely fitting over the guide posts so that the plate I5? is capable :of universal tilted longitudinal smovement thereon aszshown in Figure 177. The

bottom of the plate I62 carries a bent release plate I69 loosely pivoted on the line of bend by two headed pins I69, the flap being shown in one extreme position in Figure 13. A hole I is located in the bottom of the case NH, and the lower end of the tube I13 passes through the hole HI and rests on one corner of the release plate I93, the tube extending through a hole I19 in the cover plate I63. The disk I51 rests on and is supported by the upper end of the tube I13. A pin I19 passes through suitable holes in the case I 9| and top plate I93, and the lower end of thi pin bears against a bent portion of the release plate I69 on the opposite side of the line of bend from the tube I13. An elongated Weight I11 is loosely pivoted at one end by the headed pins I18 passing through enlarged holes in the weight, the weight having an enlarged hole I19 therethrough through which the tube 113 freely passes. In the position shown in Figure 13 the weight I11 bears on the pin I16 with the outer end IBI of the weight resting on plate I93, the opposite end I 92 being in elevated position against the heads of the pins I18.

It will be evident, from the construction so far described, that the weight I11 bearing on the pin H6 depresses one end of the release plate E99, and the opposite end of the release plate I99 bears against the lower end of tube I13 holding it in elevated position and thus holds the disk I61 in its uppermost position as seen in Figure 13. The release plate I68 has a hole I93 therethrough terminating inknife edges I84 to provide a bearing edge for the lower end of tube I13. When the disk I61 is depressed, as will hereinafter appear, it forces tube I13 downwardly against release plate I69 whereby the release plate is pivoted on pins I69, this motion being allowed by the elevation of weight I11.

The case ISI is cut out at I9I and I92 to receive a slide bar I93 having a stop pin I94 extending therethrough at one end to limit its lengthwise movement therethrough. The bar I93 is cut out on its bottom as indicated at I95 and has a pin I96 driven therein which receives a roller or catch member I91 located in the recess I95. A curved lever I99 is pivoted on a headed pin 29I riveted to the bottom of the casing "SI, and the lever I99 has a tail 292 which passes into the recess I95 in the slide bar I93. Adjacent the tail the lever I99 is cut out at 293 substantially on a circle to receive the roller I91, and it will be evident that upon sliding motion of the bar I93 to the right, that the roller I 91 engages the corner 299 and swings the lever I93 about the pin 2! as a pivot in counter clockwise direction. Once the lever I99 has been moved in counter clockwise direction, its accidental return movement is prevented by a pin 294 sweated into the lever I99 which reacts with a bent guard 295 to maintain the lever in such position. Upon motion of the bar from right to left as seen in Figure 16, the roller I91 engages the tall 292 of lever I99 and swings the lever in clockwise direction, the guard 295 being moved out of the way of pin 294 to allow this movement.

The lever I99 carries a roller 296 pivoted on a pin 291 at the free end thereof. A second or intermediate curved lever 2II is pivoted on a shouldered pin 2I2 (Figures 16 and 8) riveted in the case I6I and carries a pin 283 at its opposite end, and it will be seen that the shoulder pin 2I2 and the pin 2I3 maintain the lever 2II elevated from the bottom of recess I62 so that it will contact with the roller 296, lhe lever 2H has a cut out portion 2I5 substantially conforming to the circumference of roller 296, and which terminates in a tail 2I6. It will be evident that when the lever I99 moves in counter clockwise direction it engages the edge of the groove H5 and swings the lever 2II outwardly or clockwise about the pivot pin 2I2, and when the lever I99 is rotated clockwise the roller 296 engages the tail 2I6 and rotates the lever 2II counter clockwise or inwardly about the pivot pin 2I2.

A third or latch lever 2 I8 is pivoted in the case I9I by a headed pin 219, the pivot pins 2I2 and 2I9 being preferable but not necessarily substantially diametrically opposite. The latch lever 2H3 has a straight end portion 22I at its free end. Adjacent the pin 2l9 the latch lever 2I8 has a cut out portion 222 which is cut substan-tially on the circumference of roller 223 iournalled on pin 2I3 in lever 2I I, and a cocking piece or tail 224 is provided adjacent the groove 222. When the lever 2 is rotated clockwise the roller 223 engages the end of groove 222 and rotates the latch lever 2I3 in a counter clockwise direction around the pivot pin 2| 9, and when the lever 2 is rotated counter clockwise it engages the tail 229 and rotates the latch lever 2 I9 in a clockwise direction about the pivot 2I9. A detent pin 221 (Figures 15, 16 and 19) is riveted or otherwise secured to one corner of the release plate I68 as shown in detail in Figure 19, and extends with a loose fit through a suitable hole 226 in the bottom of casing IBI into the latch chamber I62. This pin has a flat side portion 228 adjacent its end and the opposite side of the pin is cut on a bevel as indicated at 229. When the pin 221 is in elevated position the fiat side 228 thereof is engaged by the free end 22I of lever 2I9 to prevent outward rotation thereof.

From the foregoing description it will be evident that when the bar I93 is in the position shown in Figure 16, the lever 2 will be in its position as shown, and the latch lever 2I3 will be in its full line position engaging detent pin 221. The bar I93 is thus locked against movement to the right in this position because the roller 223 engages the end of recess 222 of lever 2I9 while roller 296 engages the end of recess 2I5 of lever 2H and roller I91 engages the corner 299 of lever I99. As lever 2I6 cannot rotate it of course is not possible for levers 2H 01 I99 to rotate and the slide bar therefore is locked against movement to the right. This position .of the bar corresponds to open position of the dispensing valve as will hereinafter appear. However, when the detent 221 is depressed, this action occuring automatically when the predetermined quantity has passed through the valve as will hereinafter appear, the latch lever 2H3 is allowed to rotate to the position shown in Figure 16 by dash and double dot lines, thus allowing roller 223 on lever 2I I to clear recess 222 to allow lever 2 to rotate under urging of lever I99, and rotation of lever 2II releases roller 296 from recess 2I5 to allow lever I99 to rotate and clear corner 299 from the roller I91 thus allowing slide bar I93 to move to the right. The force for moving the bar I93 to the right preferably is provided by a spring in the valve itself as will hereinafter appear.

The dispensing valve is shown in Figure 14 in closed position. This valve comprises a casing 230 having a dividing wall 23I therein with a valve seat 232 against which a large valve 233 is adaptedito :seat;

shown in Figures 1 and .4, they will not be described. in detail except where they differ therefrom; The valve 239::hasan outlet: 235 atone end,.. and" the opposite I end 236 is' open and threadedly receives a cap .231 having. a. threaded inlet 23'8"therein:. The. cap 23"I has'four guide ribs 239 which are cut. out at their center as indicated at 24! to receive the tubular extension 242' of thevalve 233, and a'hub 244 is formed at the terminal: of the ribs 239. This hub has a .bre"245 therethrough which receives the valve stem 246" secured'to: smaller valve 234, the ribs 239 being; cut away. at 25-7 to receive therend of spring 249.. The opposite' end of the valve 234" has an. extension 25I which passes. through a hole 252 in therhub 250 offthe large valve 233.

The :extension 25I' is engaged by theend of a' curved arm :255which forms an operative conn'ection: with: the'isquared end 25301 operating stem 25B of the valve (Figures Hand. 20): This storm extends through an offset chamber 251 through? a suitable removable stuffing box ass-emJoly which: comprises aireinovabl'estuifing-box housing. 258'threa-dedat one end with spaced threaded porti'ons269 and threaded: home against the-Ifiange into the" chamber 251:. The bushing 258 has. a: packingrecessu 259 adaptedto receive suitable packing which is compressed by a gland. 26I threaded into'thepacking recess. Holes 263 are-provided in the groovezportion. 254to supply lubricant to the packing, and'lubricant is supplledt from the: exterior to. groove 264' through a suitable-opening receiving: azgrease cup or other suitable'device.

Ther squared end'2t5 receives an operating lever' 261-, and'a handwren'ch. 268 is superposed thereon and held against removal in any suitablemanner. The operating'l'ever 251' hasv a hole adjacent its outer'end and. a connectingrord 269 withr a lclevis .21 I- at its endis secure'dthereto by a clevis pin'2l2. The connecting rod' 269 hasa' similarclevis 213 at its opposite end (Figure 13') i whichisiconnectedz by' a clevis pin 2M to one end of the slide bar I93.

The..predetermining register is'similar to that shown irr Figures 1,.and to 12, except that rod 216 'swivele'd to theweight .I30ihas its lower end guided through a holev 215 in bearing bar 271' suitably-secured'to the frame H. An: emergency trip lever comprises a heavyball 218:" pressed onto' the end. of a .trip' pin 279' passingthrough -a.bushing'28fl"in housing I50. The weight of ball: 218 normally holds the rod-2l9 in its upper r1111 line position as shown-in Figure 13. The shaft l5-"hasa gear 231 thereon at its lower end whichzmeshes with a suitable gear not shown on a central. shaftop'erated by the meter.

Referringxto Figure l3, the operation of the meterrotates shaft I5 upon which worm-Bids securedywhich in turn rotates worm wheel 32 and shaft 93 to operate the predetermining counter. givensquanti'ty of fluid, the counter wheels IM' and. I65 (Figures 5; 6 and 113) are brought to the position where the notches H6; III and H2 are in alignment at the rear so that=the rollers I34; I35 and I35 fall into" these recesses and allow weight I 30 .tojfali. The weight I30 pushes. down rod TIE-against the plate I51 idepressi-ng: thesame. The weight I'I'I which is pivoted at. I'I8 bears on pin H6- and normally holds the right end of'the release plateIfiB -de- The valve member 233 has a smaller interior valve 234,. and as the valves233' and. 234 are similar in; construction with that This counter having been 'set to deliverany pressed as shown-in Figure 13, and thereby maine tains the detent pin 22'! in elevated position as seen in Figure 19. The plate I61 bearson tube I13 which rests on one end of release plate I68. When the rod 215 strikes plate I61 this plate is depressed thereby forcing the tube downwardly and depressing the left end of release plate I68 as shown in; Figure 17 to depress the detent pin 221'; this motion. being'permitted by the yielding of weight I". The depression of detent 227 releases latch lever 2I8 allowing this lever to move counterclockwise to the position shown in dot and double dash lines (Figure 16), and allows roller 223 to clear recess 222 of the lever 2I8, whereby lever 2II is allowed to rotate clockwise. This in turn allows the roller 206 to clear the recess 2i'5-of lever 2H whereby lever I99 is allowed to rotate counterclockwise to enable roller I91-to' ride over the shoulderliill which releases the slide bar I93 for movement from left to right. Sli'debar I93 is attached to operating lever of the'val-ve 236 by the connecting bar 269, and movement of slide bar I93 to the right under the action'of spring Mil-allows lever 251 to rotate counterclockwise, thereby withdrawing curved arm 255 from: engagement with extension rod 25I and allowing the spring 2G9 to close the valves 23-3 and 234 as shown in Figure 14.

The mechanism is set initially'by the operator by turning the hands wrench 263inclockwise direction to depress. extension 25! and first open valve-234' against the action of spring 249. Upon further movement of wrench 268 the lever 255 engages the hub 2550f. the valve 233 and causes this valve to -open- The rotary movement of wrench 268* transmitted to stem 255 rotates operating; lever 25! in clockwise direction, the

movement of which is transmitted bytherod-ZBS to the slide bar I93 causingthe slide bar I93 to be moved from right to left. It will :beunderstood that the settingof the -counter wheels I33, IM' and IIl51to deliver adesired quantity of fluid as previously described, has raised the rollers I34, I35 and I36-0ut of the depressions IIil, I l I and I I 2' so that they-are riding on the flange Hi9 thereby maintaining the weight I androd 261 in elevated position, the rod 216= being out of 'contact with the disk I51. This allows the weight I71 to'depressthe pin I'Ifi to- -lower the right side of the release plate I68 from the po= sition shown in- Figure 17 to that shown in Figure-13 whereby the left-end of the release plate carrying the pin 22'! is elevated-"as seenin Figure 19, and the tube I13 and plate I51 are moved to their uppermost positions. Upon movement of slide bar I93- tothe left theroller I91 engages the tail 203 of lever I99-and rotates this lever in clockwise direction whereupon roller 256 engages the tail- 2I3 of lever 2H to rotate thislever in counterclockwise direction; and roller 223 en,-. gages the tail 223 of lever 2I8. to-rotate this lever in clockwise: direction. When theend 221' of lever 2| 8 reaches pin 22'! it risesandslides over the inclined edge 229, this motion being allowed by reason of a loose fit of pin 2I9-in lever 238. The flat side 228 of the'detent pin preventsthe lever 22I from returninguntil the pin 2Z'I'is depressed by operation-of the automatic releasing means as previously described.

It will be noted that the hand wrench 26B is rotated against the action of spring 249,,the tendency of this spring being at all times to close the valve. When the hand wrench 258 is released by the operator the tendency of the spring to close'the valve is transmitted.;thr0ugh. the

operating lever 261 and connecting bar 299 to the slide bar I93 causing this bar to move slight- 1y to the right until the roller I91 engages the shoulder 200 on lever I99 whereupon further movement of the bar I93 to the right is prevented by the interengagement of levers I99, 2 and 2I8. The levers are then in the position shown in full lines in Figure 16.

Upon closing of the valves when the lever I 99 has moved counter clockwise under the action of spring 229 it strikes the tube I19 and tends to rebound. However, by the time the lever I99 has rebounded the slide bar I99 has been moved to the right sufiiciently to bring the guard 295 into such position that it is struck by the pin 294 carried on lever I99 thereby preventing this lever from striking tail MB of lever 2H on the rebound and latching lever 2I9.

Should an emergency require shutting ofl of the valve 239, the operator raises the ball 2'58 thereby depressing pin 219 against the plate IE'I to release the detent pin 221 as previously described.

The construction disclosed in Figures 13 to 20 has the advantage that the register case I69 g embodiment is therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
